Galvanized steel sheet: Most popular due to reasonable price and good rust resistance in normal environments.
Stainless steel (SUS 201, 304): Used in environments that require high hygiene, corrosion resistance or chemicals (such as food factories, healthcare, clean rooms).
Closing the system: This is the most basic use. Duct seals help prevent air from escaping or entering from the top of the duct, ensuring airflow is correctly directed through the system.
Prevent dust and insects: Sealing the duct ends helps prevent dirt, insects, or other foreign objects from entering the duct system, ensuring air quality and hygiene.
Pressure control: In some cases, duct seals are used to create a closed system, helping to maintain the necessary pressure inside the duct.
Temporary or permanent: Can be used to temporarily close an unused pipe branch, or permanently seal the end of a pipe.
Design: Square duct seals are usually shaped to match the cross-section of the duct, with edges designed to easily connect with duct flanges or types of braces.
Thickness: The thickness of the material depends on the size of the duct and the durability requirements of the system.
